Chlorine dioxide is a great and cheap water purifier

Get plastic barrels or buckets and have your gutters run into them then every rain replenishes your water to chlorinate

Could be handy. Id rather boil it

Thanks for posting as sometimes the simple things are so much better!

Yes.

Personally, I like a Berkey filter. My plan if it comes to this - Get creek, lake water, rain water, etc., run it through a t-shirt, boil it, run it through a Berkey. Probably don’t need the boiling step, but doesn’t hurt. Don’t have to filter through a shirt, but will make the ceramic filters last longer.

For anyone who was wondering, 1.5 tsp is the amound for 10 gal.

edit: 0.25oz is 7.39338242 ml https://www.convertunits.com/from/quarter+ounce/to/ml

So if you only have gallon jugs 0.75ml (just use a children's med dropper) should do the trick.

If you have to refill those 5 gallon blue water tanks for office water stands, simply do the math. 3.69ml in a dropper would do it (or about 3/4 tsp). Heck even a 5 gallon bucket would work if needed then ladle into more manageable containers.

edit 2: assuming OP was talking about bleach, this should work and is stable at room temperature.

edit 3: Here is a guy suggesting different measurements depending on the strength of bleach. u/PlumberFag seems this link below is suggesting about half of what you were stating, though a 2nd round may be needed which falls easily within your suggestion. Good advice fren.
